LETTER- SHEET ENVELOPE.

SPECIFICATION forming part of Letters Patent No. 424,413, dated March25, 1890. Application filed December '7, 1888. erial No. 292,890. (Nomodel.)

To all whom it may concern:

Be it known that we, J osnrn W. FOLLETT and LEWIS F. MARSH, citizens ofGreat Britain, and residents of New York, N. Y., and Bristol, England,respectively, have invented a new and useful Improvement in Letter-SheetEnvelopes, of which the followingis a specification.

Ourimprovement relates to what is kn own as letter-sheet envelopes, orsuch in which the envelope is integral with the letter-sheet, the twotogether being one continuous piece of paper.

The object of the improvement is to provide more letter-surface than inletter-sheet envelopes heretofore made, and to arrange for folding theletter in such a way as to conceal the writing without pasting at thesides, and to require for sealing no more trouble than the meredampening of the paste or glue of ,the sealing-flap, as in ordinaryenvelopes without letter-sheets; also, tov provide on all parts of theletter-sheet envelope, except such as reserved for the address and theletter, advertisingspaces, by the income from which the expense of theletter-sheet envelopes will be covered, so that they may be given awayto the public or sold at much lower price than ever heretofore.

The improvement will be hereinafter fully described, reference being hadto the accompanyin g drawings, in which- Figure 1 represents an outsideview of our improved letter-sheet envelope displayed. Fig. 2 is aninside view of the same displayed. Fig. 3 represents the same seen as inFig. 2, with the side flaps folded upon the main body. Fig. 4:represents the same seen as in Fig. 3, but with the first fold made fromthe bottom or foot of the sheet. Fig. 5 is a view of the same, seen asin Fig. l, the second fold from the foot being made. Fig. 6 is a view ofthe same, seen as in Fig. 5, the third fold from the bottom or footbeing made. Fig. 7 is a view of the same similar to Fig. 6, thesealing-flap being folded as when the letter is sealed.

A is the body of the sheet, and may be plain or ruled, as shown in Fig.2, for receiving the letter of correspondence.

B is a side extension of the body A, and

may be ruled like the body or left plain, as

in Fig. 2, for increasing the letter-surface, or I it may be used foradvertising-spaces, as may be desired.

0 is a side flap at the right of the body A, opposite to the extensionB, and its surface is reserved for advertising.

Extending from the upper end of the body A (see Fig. 2) and of the samewidth as the body is the address-flap D, provided with the ordinaryfolding flap or lip E of ordinary envelopes. The inside of theaddress-flap D is divided into advertising-spaces.

The entire outer surface of the sheet, with the exception of theaddress-flap D, on which is printed in the upper right corner the post;-agestamp, is divided in advertising-spaces, as in Fig. 1, the letter awherever it appears on the drawings indicating an advertising-space onthe letter-sheet, and the position of the letters a, whether rightend upor reversed or written along vertical lines, as .shown in the respectivespaces of the views on the drawings, indicate, respectively, theposition of the type in the advertisements, the reversed letters in Fig.1 appearing in their normal position when the letter is folded andsealed, as in Figs. 6 and 7.

The curved line 6 in Fig. 1 is to be printed on the sheet to indicatethe position of the gummed flap E upon the outside of the body when theletter is sealed.

The dotted lines o a s m 2 2 3 3 4 4 5 5 on the drawings should beprinted or indicated by perforations at intervals to indicate the linesalong which the sheet is to be folded.

The letter having been written, the side extension B, which is prettynearly of the same width as the body A, is first folded over the line 8m upon the body A and its edge covered up by likewise folding the flap 0upon it and the body along the lineon, as in Fig. 3. By these two foldsthe contents of the letter are covered or concealed from view andleaving exposed advertisements only. The thusfolded sheet is then foldedfrom the bottom edge 1 1 first over the line 2 2, the fold appearing asin Fig. l, then over the line 3 3, the fold appearing as in Fig. 5, thenagain over the line 4.- l, the fold appearing as in Fig. 6, and,finally, the gummed flap E folded upon the body over the line 5 5, theedge of the flap coinciding With the dotted curved line 6 and the lettersealed,the reverse side thereof traced and the folding readilyunderstood.

It Will also be seen that when the sheet is folded it cannot Withouttearing be opened at the ends, (although not gummed there, as inordinary letter-sheet envel0pes,) so as to expose to view the writtencontents.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent The combination, in aletter-sheet envelope, ofthe body A, the side extension B, nearly a the width of body A, theopposite narrower side extension 0, which extensions are of same heightas body A and fold together on and cover the surface-of body A, theaddress-flap D on the top of body A and being the Width of the foldedletter, and the ordinary envelopesealing flap E on the top of theaddress-flap D, all substantially as described.

,In testimony that We claim the foregoing as our invention We havesigned our names. each in presence of tWo Witnesses, the 8th and 22d dayof November, 1888.
